Ledgers are the permanent record of all Proposals and Actions that occur. The System Ledger is the main, default ledger for any Collective; with CoGov, other Ledgers can be created as well.
“In any decentralized governance system there is a principal tension between resilience and scalability.” This statement sums up the problem that a Collective can face in both maximizing the number or voices contributing to decisions, and maximizing the ability for the most number of decisions to be made in a timeframe that is efficient enough to be in alignment with the goals of the Collective. CoGov helps to ease the tension between resilience and scalability by allowing for other ledgers to also exist wherein Members can be assigned varying levels of Influence Currency, based on their experience or other factors. These other Ledgers can then be assigned Privileges to act on behalf of the Collective.
All details of the System Ledger are fully transparent to all collective members, and all details of other ledgers are fully transparent to all members who are assigned some level of access to that ledger. A non-system ledger cannot perform actions that directly affect system parameters unless they are given the Privilege to do so, which is an Action in itself.
